Print this page Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

problem #2

Aug 072006

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 87,000 miles


My 2002 Trailblazer transmission cooler line failed when we went to replace it we were told that both lines had to be replaced ( only 1 was bad) because GM redesigned this part if the part was redesigned then they must have realized a mistake and this should have been recalled. We were lucky we noticed ours leaking when we did. We saw smoke and stopped before a fire. Now waiting on parts to fix, dealer item only and not in stock. Trailblazer not old enough for this to be happening.

problem #1

Trailblazer 4WD 6-cyl

  • Automatic transmission

There were no events that took place before this happened. The failure was a coupling on the high pressure transmission line. The transmission fluid sprayed onto exhaust manifold and started a major engine fire. Nothing has been done at this time.
